Pompe à vide pour le stockage de filaments

Vacuum Pump for Filament StorageRecently, I upgraded all my filament storage bags to use vacuum storage. I bought an electric pump to go with them. While it did work, it pumped air out of the bags very slowly and was not very ergonomic. Despite the multitude of pumps available on the market, I must have picked the wrong one from the get-go. Moreover, I broke it on the first day while repacking all my spools. However, I ed that I had some excellent and quite efficient Parker pumps left over from a PNP SMD installer project. Considering their high performance, these pumps turned out to be perfect for filament storage.For those who might not know: most filaments are hygroscopic, meaning they absorb moisture from the air. This can lead to issues during printing, such as boiling plastic, which might make you think there’s something wrong with your printer. But that's a side note. Let's get back to the pump.Key Aspects of the Pump DesignMain FeaturesThis pump is based on a brushless motor with two independent membrane heads. These heads can operate individually, in parallel, or in series. Parallel connection increases air flow, while series connection boosts vacuum power. If you switch the inputs and outputs, you can simply use it as a pump.PerformanceThe pump’s performance is quite decent for our needs, quickly evacuating air from the storage bags. For the skeptics: yes, you could use a vacuum cleaner instead, but let’s not go there.ModificationsBarbs and Fittings: The pump originally came with standard barbs, which I removed. I drilled holes, tapped them to M5 thread, and installed quick-disconnect pneumatic fittings.Mufflers: I added mufflers to the pump outlets, considerably reducing noise.Power Consumption: The pump operates on just 250 mAh at 12V. I decided to use a battery with a boost converter module, and the charge lasts quite long.Control: The pump is turned on with a TTP223 touch sensor module, which has multiple operating modes depending on the jumpers used. You'll also need a small N-MOSFET and a couple of resistors 10k and 0,1k.Charging ModuleI use a LiPo battery charging module that I designed and manufactured myself. Although it’s not commercially available, there are alternatives you can use. Links to these are provided in the general parts list.Printing PartsSome parts require s. I created highly detailed s with minimal offsets. Pre-configured files for BambuLab and Creality K1 printers are included , but they can be adjusted for other printers.I used eSUN ABS+HS plastic for its ease of use and matte finish. The pump damper is made from the same manufacturer’s TPU. The feet are also made from soft plastic, and silicone rings are used between the casing and damper to further reduce vibrations and noise.Housing AssemblyThe housing consists of a frame and a false that hides all the fasteners. This design ensures simplicity in assembly and a clean look without any visible screws. My inspiration came from LEGO constructions, which enable easy-to-assemble and robust housings.Vacuum Suction CupI paid special attention to the vacuum suction cup design, as the store-bought pump was quite inconvenient to use. The new suction cup mimics the shape of the hand, making it much more comfortable to use. It's designed for right-handers, but if you're left-handed, you can mirror the model in the slicer. The suction is sealed with a silicone ring, 2.5mm thick with an inner diameter of 32mm.ConclusionCompared to available market options, the cost of components for my vacuum pump might seem high. However, since all the components were already on hand, I decided to create this device. The quality of the pump’s operation is significantly higher than anything I’ve seen on the market. Creating a high-quality, reliable device with the materials you have will make your filament storage experience much more enjoyable and efficient.I hope this project proves useful for you.
